787 fuel leaks: Over the weekend, a Japan Airlines 787 experienced its second fuel leak in less than a week. After its 787 leaked about 40 gallons of fuel in Boston, the same JAL also leaked fuel in tests over the weekend. The incidents have prompted an investigation by Japan’s transport ministry, Reuters reported Monday.

Airlines and the 787: Dreamliner reliability issues have forced airlines to take unusual steps to mitigate potential problems, The Wall Street Journal reports. An example: United had two 787s ready as backups when it launched 787 service from Los Angeles to Tokyo.

Lithium-ion batteries: The Dreamliner’s lithium-ion battery has got a lot of attention after Monday’s fire. Scott Hamilton, with Leeham Co., takes a look at other aircraft that use, or will use, the same type of battery including Airbus’ A380 and A350 jets.

UPDATE at 1:45 p.m.

NTSB investigators have done several examinations and scans of the 787’s lithium-ion battery to document its condition. This week, though, they plan to disassemble the battery. The investigative team includes representatives from the Federal Aviation Administration; Boeing; US Naval Surface Warfare Center’s Carderock Division; Japan Airlines; GS Yuasa, which manufactured the 787’s lithium-ion battery; and Thales Avionics Electrical Systems, the manufacturer of the auxiliary power unit and charger system.
